Combine stacks of ammo when dragging#17

Instead of having to split ammo to make it stack better, make it so dragging a stack to another will auto stack it,

ex, dragging 50 ammo to a stack of 60 would make the stack you dragged turn into 10 and the stack you dropped into go to 100

right click - stack all. problem solved

having to right click and stack all is pretty anoying when they could just make it where when you use shift left click to move somthing it auto stacks if you have a partial stack already in your inventory

avoiding Right click sounds better/faster like add hot alt key for stack all command?

Also please let us use the scroll wheel to quickly adjust the number when splitting stacks.
